Abstract:Beginning with the analysis of the basic flow pattern and discharge characteristics of the horizontal vortex and inner energy dissipating tunnel with inlet shaft, the expressions of velocity distributions in the tunnel have been supposed and established. Axial velocity, circumferential velocity and related hydraulic characteristics have been studied according to experimental data. This study will be useful for the hydraulic analysis, calculation and design of the tunnel.
Keywords:inlet shaft  horizontal vortex  velocity distribution
